Where are star-delta and delta-star transformers used?

star- delta normal used as step up transformer , and delta star used normally as step down transformer , precisely for distribution transformer in order to reduce the voltage level with the ratio and to add a neutral line from the star point. read more

Distribution transformers are connected in delta-star. This arrangement requires 3 conductors in the high voltage side and 4 in the low voltage side, as well as it provides the star point conductor as a neutral point. This can serve single phase as well as three phase loads. read more
